In the relining of brake ban ds, it the common practice to place the lining in posia 'n h i a ala dri l came sink holes in the'lining byj introducing adrill and countersink through the holes in the band so as-toyhave proper registration. Registration of the drill with the band holes has been tedious and inconvenient. The present invention contemplates the provision of a machine having convenient registration means for guiding the drill. Registration means is provided for clutches. It is another object of this invention to provide a detail of structure, whereby the proper registration means for a particular kind of'work may be presented in operating position without interference. In addition to the broader objects of this invention, there are certain details of structure and design whereby, a simple, durable, easily operated mechanism is obtained.

These objects together with other objects and corresponding accomplishments are obtained by means of the embodiment of my invention illustrated in the accompanying drawing, in which:

Fig. 1 is a side elevation of a complete machine; Fig. 2 is a plan view of the machine; Fig. 3 is a face view of the machine on an enlarged scale; and F ig. 4 is a fragmentary tion means in another position.

Referring more particularly to the drawing, 5 indicates a supporting frame having an upright portion 6 to which an electric motor 7 is secured. The motor is mounted in a position such that the shaft is verticaland extends through bearings in the base of frame 5. The base has an open space so that an upper table is provided and room below it for the gearing, belts, and the like. Secured to the motor shaft is a. pulley 8. A vertical shaft is journalled' in the front end of the base. Fixed thereon'is a pulley 9. Pulleys Sand 7, Screw 26. The new similar to Fig. 1 showing the reg1stra- 9 tog-ethos hymen-1b. The shaft.

fM l tedJt l th rtr a is aiz gistfa iefi tia fif fleisstead m' eare nsed withv a ori'z'ontal arm so as to overhang the coulitersink drill when turned to the position shown in Fig. 1. It is provided with a pin 18 rotatably extending through a frame, the pin being threaded at its lower end, and mounted upon the pin is a wing nut 19. The standard 17 rests upon an elevation 20 on the table, the elevation having indentations. The standard has teeth 21 to rest in the indentations. The standard is arranged to be turned through 180, andthe teeth resting in the indentations fix the position. Formed at the end of the horizontal arm of standard vl7 is a sleeve 22 for slidably receiving a centersition shown in Fig. 1, pin 23 will be in line with the drilll12. The centering pin may be raised and lowered and held in'selected-po sition by a set'screw 24. Slidably extending through the standard in tion is the centering pin 25, arranged to be held'in selected position by'means of a set parts are so arranged that by unloosening nut 19, the standard may be turned so as to present the end of centering pin 25 above the drill or the end of centering pin 23 above the drill andthen locked in sltion.

Suppose a brake band is to be relined. Pin 23 is adjusted to a position. dependent upon the thickness of the brake band andlining extends forward the band being uppermost. The band is then moved so that the hole is in line'with and in registration with pin 23. The correct regisr qnmay be obtained byliftingthe band ugtil thecentering pin enters the hole, then;

the band upon the drill, which is dropping bore therethrough and to countercaused to sink the hole. If a cone clutch is to be relined, thumb nut 19 is loosened and the standard 13 turned to the position shown in Fig. 4 then locked. In this position, the centering pin 25 yand the centering pin 23'is out of the way. The clutch is placed in position with the end ofthe pin 25 in registration withthe hole in the clutch on the inside. The

clutch is now forced downwardly, the drill boring a hole through the clutch linin and countersinking the latter. The depth'a justment forcountersinking and adjustment of thecentering pin i'smade asbefore described.

-What I claim is; 1. Anmchine of the class described comprising: a base; a countersink drill mounted to extend upwardly therefrom a depth stop embracing said drill and having a post for raising and lowering said stop, said post being mounted upon said base; means acting 7 upon said *post for adjustably raising and lowering said stop; an upright centering apin standard mounted to be turned on said base about a vertical axis and having an overhanging arm .provided with a depending adjustable pin fixed thereto in llIleNVltlL said drill; a centering, pin adjustablymounted on said standard and extending laterally of said drill; andmeans to lock said standard in severtically adjustable pin slidably mounted in said sleeve in line with said drill; means to lock said pin in selected position; a horizon- V tal centering pin slidably mounted on said standard and extending laterallyof said drill means to lock said horizontal pin in selected positions; and means to lock said standard in selected positions.

In witness .thatI claim the foregoing I have hereunto subscribed my name this 24th day of September, 1924.
